<p>An operating mechanism is disclosed for building components such as windows, doors and the like to allow reliable connection between the handle and the actuating element without resort to any tool. The operating mechanism includes at least one handle and an actuating element that can be made to engage the handle in a mutually irrotational manner. A blocking device is situated between the handle and the actuating element and is designed so that the actuating element is insertable in a first direction into the handle whereas its displacement in the opposite direction is blocked.</p> |
